QUESTIONS UNDER STUDY After years of advocating ABC (Airway-Breathing-Circulation), current guidelines of cardiopulmonary resuscitation (CPR) recommend CAB (Circulation-Airway-Breathing). This trial compared ABC with CAB as initial approach to CPR from the arrival of rescuers until the completion of the first resuscitation cycle. METHODS 108 teams, consisting of two physicians each, were rand...
The artificial bee colony (ABC) algorithm is a popular swarm based technique, which is inspired from the intelligent foraging behavior of honeybee swarms. This paper proposes a new variant of ABC algorithm, namely, enhanced ABC with solution acceptance rule and probabilistic multisearch (ABC-SA) to address global optimization problems. A new solution acceptance rule is proposed where, instead o...
Approximate Bayesian computation (ABC) have become an essential tool for the analysis of complex stochastic models. Grelaud et al. [(2009) Bayesian Anal 3:427-442] advocated the use of ABC for model choice in the specific case of Gibbs random fields, relying on an intermodel sufficiency property to show that the approximation was legitimate. We implemented ABC model choice in a wide range of ph...
Sequential techniques can be adapted to the ABC algorithm to enhance its efficiency. For instance, when Sisson et al. (2007) introduced the ABC-PRC algorithm, the goal was to improve upon existing ABC-MCMC algorithms (Marjoram et al., 2003). While the ABC-PRC method is based upon the theoretical developments of Del Moral et al. (2006), the application to the setting of approximate Bayesian comp...
Approximate Bayesian Computation (ABC) is a family of statistical inference techniques, which is increasingly used in biology and other scientific fields. Its main benefit is to be applicable to models for which the computation of the model likelihood is intractable. The basic idea of ABC is to empirically approximate the model likelihood by using intensive realizations of model runs. Due to co...
در این پژوهش تأثیر اتصال دو به دوی انتهای لاترالها بر خصوصیات هیدرولیکی سیستم آبیاری قطرهای بررسی شد. برای انجام آزمایش، یک سیستم آبیاری قطرهای در قطعه زمینی مسطح به ابعاد 80 متر در 90 متر در مزرعة تحقیقاتی دانشگاه زنجان ایجاد شد. آزمایش در دو شرایط بدون اتصال (N.C.) و اتصال دو به دو (P.C.) انتهای لاترالها و در سه فشار کارکرد 5/0، 0/1 و 5/1 بار انجام گرفت. قطرهچکان مورد استفاده از نوع طولا...
Internal organs in vertebrates show distinctive left–right asymmetry. To establish left–right patterning, creation of a leftward flow plays a critical role. However, how this flow function or how this flow is sensed is still debated, because a flow sensor itself has not been identified yet. Here we show a medaka mutant abecobe (abc), isolated by our recent ENU-mediated mutagenesis screening wit...
The natural behaviour of the honeybee has attracted the attention of researchers in recent years and several algorithms have been developed that mimic swarm behaviour to solve optimisation problems. This paper introduces an artificial bee colony (ABC) algorithm for the vehicle routing problem with time windows (VRPTW). A Modified ABC algorithm is proposed to improve the solution quality of the ...
RNA interference (RNAi) mechanisms are conserved and consist of an interrelated network of activities that not only respond to exogenous dsRNA, but also perform endogenous functions required in the fine tuning of gene expression and in maintaining genome integrity. Not surprisingly, RNAi functions have widespread influences on cellular function and organismal development. Previously, we observe...
The Artificial Bee Colony (ABC) algorithm is one of most popular stochastic, swarm based algorithm proposed by Karaboga in 2005 inspired from the foraging behaviour of honey bees. ABC has been applied to solve several problems in various fields and also many researchers have attempted to improve ABC’s performance by making some modifications. This paper proposes a new variant of ABC algorithm b...
